E-bike Conversion Kit Modular Mounting for Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing e-bike conversion kits are often complex, require specialized tools, and cause balance issues due to bulky components, making them difficult and unsafe for consumers to install on regular bicycles, and often necessitate modifications to the bike's pedal and sprocket assembly.
Innovation Solution
The e-bike conversion kit provides a portable electric motive power unit with a demountable motor mount bracket and battery mount bracket that can be easily engaged with a regular bike's frame and handlebars, allowing for mid-drive functionality without removing or modifying existing bike components, using a freewheeling sprocket assembly to provide electric assistance without altering the bike's balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If prior art e-bike conversion kits use bulky components to provide mid-drive functionality, then electric power transmission is achieved, but weight distribution becomes unbalanced causing directional control and balance issues
Solution Approach 1:
The conversion kit is divided into separate modular components: a motor assembly, a bracket assembly, and a battery pack. Each component can be independently positioned and adjusted to optimize weight distribution. The bracket assembly can be mounted at different locations on the bicycle frame to balance the weight distribution while maintaining electric power transmission capability.
Solution Approach 2:
The patent introduces adjustable mounting positions in multiple dimensions (vertical, horizontal, angular) for the motor and battery components. This allows the weight distribution to be optimized by positioning components in three-dimensional space rather than being fixed in a single plane, thereby maintaining balance while providing electric power transmission.
2Power
If prior art e-bike conversion kits require removal or modification of bike components to provide mid-drive functionality, then electric motor engagement is achieved, but installation complexity and time increase
Solution Approach 1:
The invention extracts the motor and battery components from the bicycle's existing structure and introduces them as separate, non-invasive additions. The motor assembly is mounted on a bracket that attaches to the bicycle frame without requiring removal of existing components, and the battery pack is mounted separately, thereby achieving motor engagement while minimizing installation complexity.
Solution Approach 2:
The bracket assembly serves as an intermediary component that facilitates motor engagement without directly modifying the bicycle's original structure. The bracket attaches to the frame and provides a mounting surface for the motor, acting as a mediator that enables electric power transmission while avoiding complex modifications to the bicycle's existing components.
3Reliability
If prior art e-bike conversion kits use specialized tools and technical knowledge for installation, then proper fitting is achieved, but accessibility and ease of installation decrease
Solution Approach 1:
The conversion kit is designed with self-aligning features and simple fastening mechanisms that allow users to install the components without requiring specialized tools or advanced technical knowledge. The bracket assembly and battery pack mounting systems are designed to be self-positioning, enabling users to perform the installation themselves while maintaining proper fitting and reliability.
4Power
If prior art e-bike conversion kits replace pedal and sprocket assemblies to provide mid-drive functionality, then electric motor engagement is achieved, but the bike's original balance and handling characteristics are altered
Solution Approach 1:
The invention extracts the motor and battery components from the pedal and sprocket assemblies, mounting them separately on the bicycle frame. This separation allows the motor engagement to be achieved without replacing or modifying the original pedal and sprocket components, thereby preserving the bike's handling characteristics while providing electric power transmission.
